Comment 8 for bug 387738

Here's another instance. I set the location for a blind member of my nunit-dev team to Seattle, thinking he was located there. He told me he is actually in Youngstown, Ohio. I zoomed the google map (satellite view) so I could see both Washington and Ohio and dragged him
to Ohio. Then I zoomed in without clicking update and moved him to Youngstown. I clicked update and he ended up somewhere in Siberia although his time zone was set correctly.

I moved him back to Ohio using the same procedure - two moves at two resolutions - and he was again in Siberia.

Finally, keeping the map at a relatively close resolution, I panned from Siberia back to Ohio and clicked on Youngstown, clicked once on the map and then clicked update. That worked.

I suggest experimenting with multiple moves (and possibly zoom levels) before updating.
